image update at a label

[wilhelmO]

Hello and good afternoon.
I'm new to python an Tkinter. My task : a triggered camera writes 12 images every
70 seconds in a specific folder. The newest 12 images should be visible in a frame at
12 labels ( labels are able to display images ? ). I made two small programms.
One shows 12 images ( even the newest , as disered ), but then thats all , no update
when newer images comes in. The second loops infinite ( I made print statements which
prints numbers, to see the sequence of the actions ) , but show never any image at a
label. Is there someone with time and knowledge to help me ? !!

Here my code :

import Tkinter as tk
from PIL import Image, ImageTk
import os

ROW = 3
COLUMN = 4
TITLE = "TK 5 FormenScan"
IMAGE_PATH = "C:/Python26/AVT/"
RESIZE_IMAGE_WIDTH = 200
RESIZE_IMAGE_HEIGHT = 130


class Image_Viewer(tk.Frame):
    def __init__(self, root):
        tk.Frame.__init__(self, root)
        print '1'
        self.bilder()
        
    def bilder(self):    
        self.images = self.load_images()
        print '2'
        for row, images in enumerate(self.images):
            print'5'
            for column, image in enumerate(images):
                print'6'
                tk.Label(self, image = image).grid(row = column, column = row)
        self.after(2000,self.bilder())     
        
        
    def load_images(self):
        images = sorted(os.listdir(IMAGE_PATH),reverse=True)
        print'3'
        sorted_images = list()
        print'4'
        for i in xrange(ROW):
            print'7'
            l = list()
            for i in xrange(COLUMN):
                print'8'
                l.append(ImageTk.PhotoImage(Image.open("%s%s" %(IMAGE_PATH, 
                    images.pop())).resize((RESIZE_IMAGE_WIDTH,
                    RESIZE_IMAGE_HEIGHT))))
            sorted_images.append(l)
        return sorted_images
      
    
if __name__ == '__main__':
    root = tk.Tk()
    root.title(TITLE) 
    image_viewer = Image_Viewer(root)
    image_viewer.pack()  
    root.mainloop()

please , excuse my poor englisch , it's not my natural language. To make it worse ,
I'm a doing image processing for industrial purposes and not a programmer.

You could perhaps store the labels like in

from itertools import product

    def indices(self):
        return product(xrange(ROW), xrange(COLUMN))

    def create_labels(self):
        self.labels = list(list() for i in range(ROW))
        for row, column in self.indices():
            label = tk.Label(self)
            label.grid(row = column, column = row)
            self.labels[row][column] = label

then update the labels with configure() like in

def bilder(self):    
        self.images = self.load_images()
        for row, column in self.indices():
            self.labels[row][column].configure(image = self.images[row][column])
        self.after(2000,self.bilder())
